LQPECIFICATIO'N forming part of Letters Patent No. 475,543, dated May24, 1892.

Application filed October 14,1891. Serial No. 408,651. (No model.)

To all whom it may concern:

Be it known that I, JACOBS. DETRICK, a citizen of the United States,residing at Baltimore city, in the State of Maryland, have inventedcertain new and useful Improvements novel features of construction andcombinations of parts hereinafter described and claimed.

The invention is illustrated in the accompanying drawings, in which-Figure 1 represents a front elevation of the a complete machine; Fig. 2,an enlarged detail,

of the upper portion of the inclined tool-head,

slideway, and head; Fig. 3, a section on line 3 3 of Fig. 2, alsoshowing the horizontal slideway in section; Fig. 4, a similar section onthe line 4 at of Fig. 2; Fig. 5, a similar section I on the line 5 5 ofFig. 2; Fig. 6, a face view of the head, which carries the upper end ofthe inclined slideway.

The letter A designates the upright posts, which have vertical slidewaysB; O, the crossbeam supported by said posts and having the horizontalslideway D; D, the tool-head on said slideway; E, the bed, and F thereciprocating platen. Beside the horizontal and vertical slideways Iarrange an inclined or angular slideway at each side of the platen, asfollows: A head G is fitted and moves on the horizontal slideway and asimilar head G on the vertical slideway, and these two heads carry theinclined slideway I, which extends from one to the other and isconnected with both. At the upper end of this inclined slideway is apartly-circular plate J which fits against the head G and is connectedtherewith by bolts a, the heads a of which are confined in a circulargroove b in the said head G, as illustrated in Fig. 5. The bolt-headsare entered-through an enlargement 1?. (Shown in Fig. 6.) These boltsextend through the said plate J and have suitable nuts and washers totighten them. The lower end of the inclined slideway is connected to thehead G by a longitudinal slot (Z, and a bolt or stud d projects from thesaid head through the slot adjusted on their slideways B and D. Thisadjustment of the said head G G is accomplished by the screw-shafts 7' kon the horizontal slideway D and similar shafts it on the verticalslideways.

The slideway I receives a tool-head K, the feed of which is through thefollowing-described mechanism: A screw-shaft 6 runs through thetool-head lengthwise of the slideway and carries a miter-pinion f at itsupper end, which pinion gears into a similar pinion g on the outer endof a stud h, extending transversely through the head G in a suitablebearing h. This stud has on its opposite or inner end anothermiter-pinion i, which gears into a similar pinion Zon a spline-shaft m,extending lengthwise of the horizontal slideway D, said pinion, however,being carried by the head G in a bearing a on the rear side of thelatter.

Through the gearing above described the turning of the spline-shaft mactuates the screw-shaft e to feed the tool-head, and it will beobserved that the relation of this gearing remains the same to whateverposition the head G may be moved, the pinion Z sliding on thespline-shaft,but alwaysturning therewith, owing to the spline.

The tool-head D on the horizontal slideway is fed by the usualscrew-shaft o, and the latter and also the spline-shaft m are actuatedby a reciprocating rack H in the well-known way.

The screw-shaft 6 may be thrown out of gear as follows: A rod 10 entersits upper end to the point Where the pinion f is located, and at thispoint the shaft is slotted transversely, as at q. A pin 7' extendsthrough this slot and also through the rod p and pinion f, the latterbeing free to slide on the screw-shaft. The rod at its upper end has aknob s, with an inclined cant-like under surface, which engages acorresponding surface on a tubular projection s from the upper endportion of the slideway. It will be seen that upon turning the knob s itrides up on the projection s and draws the pinion f into gear, the saidknob being held on the rod 10 by a nut t, and upon turning said knob inthe opposite direction the said pinion will slide down on thescrew-shaft and out of gear, the slot q being of sufticient length topermit this movement.

In Fig. 1 a piece of Work W is shown in the machine, which serves toillustrate the kind of surfaces designed to be planed by the employmentof my new arrangement as herein described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, .is

1. In a metal-planer, the combination of a horizontal slideway, avertical slideway, a: slideway having its ends suitably connected I withthe horizoutaland vertical slideways, respectively, so as to admit ofits adjustment to diiferent inclined positions, and a tool-head E onsaid latter slideway. j

'2. In a metal-planer, the combination of a; horizontal slideway, avertical slideway, a head on said horizontal slideway, a head on saidvertical slideway, an inclined slideway carried by said two heads andadjustable to diiferent angles by moving the heads on their respectiveslideways, and a tool-head on the s inclined slideway.

3. In a metal-planer, the combination of a horizontal slideway, avertical slideway, a head on said horizontal slideway, a head on saidvertical slideway, an inclined slideway carried by said two heads andadjustable to diflerent angles by moving the headson their respectiveslideways, said inclined slideway s connected to said heads by means ofbolts which engage suitable slots, whereby such ad- 4 j ustment may behad, and a tool-head on the inclined slideway.

4. In a metal-planer, the combination of a;

horizontal slideway, a vertical slideway, al head on said horizontalslideway, a head on 1 said vertical slideway, an'inclined slidewaycarried by said two heads and adjustable to dilferent angles by movingthe heads on their respective slideways, the upper end of said inclinedslideway being connected to the head on the horizontal slideway by boltswhich engage in a circular slot in the said head and the lower end'beingconnected to the head on the vertical slideway by a bolt which projectsfrom said head and engages a slot in the inclined slideway, and a toolhead on the inclined slideway.

5. Ina metal-planer, the combination of a horizontal slideway, avertical slideway, a head on said horizontal slideway, a head on saidvertical slideway, an inclined slideway carried by said two heads andadjustable to difierent angles by moving the heads on their respectiveslideways, a tool-head on the inclined slideway, a spline-shaft in thehorizontal slideway, a screw-shaft in the inclined slideway engaging thetool-headthereon,and 7o suitable connectinggear between the two, wherebythe screw-shaft is actuated by the turning-of the spline-shaft.

6. In a metal-planer, the combination of a horizontal slideway, avertical slideway, a head on said horizontal slideway, a head on saidvertical slideway,an inclined slideway carried by said two heads andadjustable to different angles by moving the heads on their respectiveslideways, a tool-head on the inclined slideway, a spline-shaft in thehorizontal slideway, a screw'shaft in the inclined slideway engaging thetool-head thereon, a pinion on the spline-shaft carried by the head onthe horizontal slideway, a pinion on the screw-shaft, and a studextending through said head and having pinions on its opposite endswhich gear into the two pinions aforesaid, re-

spectively.

In testimony whereof I afiixmy signature in 0 the presence of twowitnesses.
